What important contact lens parameter must be considered for an aphakic patient?

For an aphakic patient, the inclusion of a contact lens with a ultraviolet (UV) inhibitor is particularly important due to the absence of the natural lens, which normally provides some level of UV protection. Aphakic individuals have an increased risk of UV-related eye damage, including cataracts and retinal diseases, because their eyes are fully exposed to UV light without the filtering effects of the lens. By selecting contact lenses that incorporate UV inhibitors, eye care professionals can help protect the aphakic patient's retina from potentially harmful UV radiation.

While other parameters such as contact lens material, contact lens solution, and edge thickness are relevant in the overall fitting and comfort of contact lenses, they do not specifically address the unique needs for UV protection in aphakic patients. Thus, the presence of a UV inhibitor is a critical consideration in ensuring the long-term ocular health of these individuals.
